Synthesis of 5-amino-1-aryl-1H-pyrazole-4-carbonitriles was performed by direct condensation of(ethoxymethylene)malononitrile and aryl hydrazines.The resulting N,N-containing heterocycles possess insecticidal properties relative to microlepidoptera species, plant phatogens. The insecticidal activity of four novel synthetic N-aryl pyrazoles to Tuta absoluta larvae was assessed. Fipronil, a well-known aryl pyrazole insecticide, was also tested as the positive control.

Synthesis of 5-amino-1-aryl-1H-pyrazole-4-carbonitriles was performed by direct condensation of(ethoxymethylene)malononitrile and aryl hydrazines.The resulting N,N-containing heterocycles possess insecticidal properties relative to microlepidoptera species, plant phatogens. The insecticidal activity of four novel synthetic N-aryl pyrazoles to Tuta absoluta larvae was assessed. Fipronil, a well-known aryl pyrazole insecticide, was also tested as the positive control. A generalized linear model reported significant differences in efficacy and tomato leaf consumption among the different treatments. Fipronil treatment was the most effective one (100% mortality after 48 h), followed by 5-amino-1-phenyl-1H-pyrazole-4-carbonitrile treatment (3c) (75% mortality after 48 h) and 5-amino-1-(2,6-dichloro-4-(trifluoromethyl)-phenyl-1H-pyrazole-4-carbonitrile treatment (3b) (60% mortality after 48 h). These compounds, with simpler structures than Fipronil could be used as novel insecticides.
